A veto is the power to stop an official action, especially the passing of legislation. Countries that can use veto power are China, France, Russia, the United Kingdom and the United States. Veto power can be a good and bad thing. When it comes to veto power, I don't believe that right or wrong is at risk. In democracies, the majority rule is used to decide what decisions should be taken. So, if there are 100 people in a democratic unit and 51 of them say "yes," we say "the majority rules," and the "Yes side" wins the vote. Obviously, in a unit of two, if the participants disagree on an issue that needs a vote, they will never be able to reach a majority. As a result, groups that need votes set up ODD total numbers for themselves.
